EGG-TEfi'lER.

Specification of Letters Patent.

Application filed August 80, 1809.

Patented Sept. 13, 1910.

Serial No. 515,207.

To all whom it may concern:

Be it known that I, \VILBnRT Roonns, a citizen of the United States,residing at Brookville, in the county of Franklin and State of Indiana,have invented a certain new and useful Egg=Tester, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to egg testers, the object of the invention beingto provide a simple, practical and economical device for testing orcandling eggs.

lVith the above general object in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings Figure l is a perspective view of an eggtester embodying the present invention. Fig. 2 is a verticallongitudinal section through the same.

Referring to the drawings, 1 designates a suitable supporting base uponwhich the remainder of the device is mounted. Extending upward from thebase are suitable parallel supporting plates 2 and 3-3 arranged at asuitable distance apart and provided with oppositely extending bottomflanges 41 connected to the top of the base by means of suitablefasteners 5. The space between the plates 2 and 3 is bridged by means ofa housing 6 which is substantially elliptical in vertical cross sectionas indicated in Fig. 1 and of sufficient size and length to contain anelectric lighting device 7, in Fig. 2. This electric lighting device 7is of the conventional form and provided at one edge with a press button8 which operates suitable contact points in electrical connection with acontained battery thereby producing a current of electricity in afilament or bulb which is located within the body of the device andbehind a lens 9, the arrangement described serving to produce a flash oflight through the lens.

The housing 6 is closed at one end by means of an oblong front plate 10and this plate is provided with an opening extending around the lens 9of the electric lighting device 7 and said opening is surrounded bymeans of an outwardly flaring or frustoconical nozzle 11 forming a restor seat against which the eggs may be placed one at a time, while heldin the hand between the fingers. Extending upward from the housing 6 inline with and above the press button 8 is a tubular extension 12 closedat its upper end by means of a removable cap 13. This cap is providedwith a central hole through which operates a plunger stem 14 having apush button or head 15 at its upper end. At its lower end the stem 14 isadapted to bear against the press button 8 of the electric lightingdevice contained in the housing so that when said stem is pressedinward, the push button 8 is operated for the purpose referred to.lVithin the extension 12 is a cross bar 16 formed with an opening toserve as a guide for the stem 14 while between said bar 16 and asuitable stop or shoulder on the stem 14, there is arranged a plungerreturn spring 17 which normally upholds the plunge and allows the pushbutton 8 to be elevated by means within the electric lighting device 7.The back of the housing is closed by means of a. shutter 18 having afriction flange 1!) insertible in the adjacent end of the housing and aspring 20 secured to the inner face of the shutter and adapted to bearagainst the adjacent end of the device 7 to hold the latter in aposition with the push button 8 in alinement with the plunger stem 14.

It will be understood that the eggs are placed one at a time against andin front of the nozzle 11, and while in such position the plunger stem14 is depressed, thereby flashing light through the body of the egg in amanner similar to the ordinary candling operation, but giving, however,a more brilliant and effective light for the purpose.

I claim In an egg tester, the combination of a holder comprising asupporting base, bracketplates extending upward therefrom and securedthereto, a housing supported by said plates and closed at one end andhaving a removable cover at the'other, an outwardly flaring nozzleconnnunicating with a central opening in the closed end of the housing,a tubular extension projecting upward the lamp and arranged to lie inthe path of from said housing, a spring sustained the plunger stem. 10plunger stem operating through said eX- In testimony whereof I afliX mysignature tension, and an electric flashing lamp emin presence of twowitnesses.
